Charmast Power Bank Quick Charge 10400mAh USB C Power Bank Ultra Slim Portable Charger LED Display Power Pack Compatible with Smartphone iPhone Huawei and More

This power bank charges devices quickly, which is really convenient when you need a fast boost. It’s lightweight and easy to carry around, making it perfect for on-the-go use. The only downside is that its battery doesn’t last very long, so you may need to recharge it frequently. Overall, handy for short-term use but not ideal for extended power needs.

Great wee powerbank. Being able to see state of charge in % is useful, and it can poer 3 devices (2xUSB A and 1xUSB C) at the same time. You can even charge it (via micro USB) at the same time. I use it as a UPS for my security camera and alarm system by leaving them both plugged in to the USB A ports, while charging via USB C.

Understanding my ratings: Unlike some reviewers I do not grant five stars simply because a product is as advertised. Three stars for meets expectations/adequate. Products lose stars for failing to meet expectations but gain stars for going above and beyond. Purchased in April 2023 for £12.99. For this price the product is good value. The power bank is solidly built. As other reviewers have noted it can take a while to charge the power bank, but that's only to be expected for a 10400 mAh battery with a maximum charge rate of 15W. I have two of these and they take around seven hours to charge from empty to full, when charging at 12W. Sure, that's longer than the superspeed charging some newer phones are capable of but such charging should only be done infrequently, when absolutely necessary, and comes at a price. For this product the charging speed is adequate, and means you can easily charge the power bank overnight. We must also bear in mind that slower charging is better for the health of the power bank's batteries. If you absolutely need a power bank which will charge faster you will need to look elsewhere and be prepared to pay considerably more for it. My primary phone has a 3300 mAh battery. This means I can get three full charges from the power bank, so with the phone fully charged and one power bank I'm looking at four days use without needing to find a way to charge either the phone or power bank. With two power banks that goes up to seven days, which is plenty for a whole week away. Perhaps the key feature of this power bank is the twin seven-segment LED display showing the current charge in the power bank. This is far superior to the four-part indicators on many other power banks and is what 'sold' the product to be in the first place. The LED display means you can easily judge how much charge remains, how many more charges you can get out of it, and a more accurate estimate of how long it will take to fully charge the power bank than you would get from one of the lesser power banks with just the 25%/50%/75%/100% indicators (like my previous power bank). The display works well and displays in 1% increments. The power bank was supplied with a soft draw-string pouch. This was unexpected and will help keep prevent the power bank from being scratched, although the pouch isn't of a hard-wearing material, so will have its limitations. The pouch is large enough to accommodate both a power bank and a small charging cable, keeping everything neat. The thing which led me to seek a replacement for my previous power bank was that the charging socket had become damaged. Because this power bank has two sockets to charge from, if one becomes unreliable you will still have the other available.

It really charges your phone and other devices really quick

I got this to charge my phone on the go and it hasn't disappointed. Its slim and small enough to slip in to a small handbag or even a pocket and looks stylish. It charges multiple devices at once and charges them quickly. Only down side is how long the power bank takes to charge up itself. however this wouldn't stop me buying it again as it lasts a long time and i have had multiple charges from this power bank

Unlike some power banks which make extravagant claims and pack up after a few charges, this one is modestly priced, well presented, reliable and comes with a useful carrying bag. The digital display gives an accurate percentage readout of the state of charge/discharge. The choice of USB C or micro USB is useful: I charge mine on solar power and find that it will refuel my Moto phone at least twice. So far, it has proved very reliable. It does take some hours to charge, but, because it outputs DC rather than a modified sine wave, it is faster than a mains adapter, and instantly available, when charging the phone or other device.

Very solid product works well with all devices

Arrived whiskey looks like image charges items fast

Ik gebruik de powerbank voor mijn S10 en het werkt prima. Quickcharge functie is ideaal voor onderweg en de powerbank laadt snel op met de usb-c port.

De charmast is zeer scherp geprijsde powerbank die 10400mAp in een zeer strakke en compacte behuizing stopt. Zeer tevreden
